Create contracts with Slack & Notion
Fires the moment a webhook arrives across Slack, Notion and Telegram, parses the incoming file into rows, then branches on the check before anything is written. Built for expenses, around a "Download Source File" step, in 13 documented nodes.
Create contracts with HTTP / REST API and Notion end to end. An original, ready-to-import n8n workflow built around the 'Document Generation' pattern for finance & banking. It fires on a webhook and orchestrates 13 nodes across Slack, Notion, HTTP / REST API. Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. Nothing slips through the cracks.
Key benefits
- ✓Keeps Slack and Notion in step for expenses, without anyone re-typing a row
- ✓A failed Slack or Notion call is retried rather than dropped, at any of the 13 nodes in this expenses build
- ✓Fans the same result out to Telegram in the same run, for expenses
- ✓Pinned sample data ships with it — run all 13 nodes for expenses before wiring Slack
- ✓13 nodes, each with a doc card explaining what it does for expenses
Use cases
- →Teams keeping Slack and Notion aligned by hand for expenses
- →Pushing expenses events into Slack and Notion the moment they land, not on the next poll
- →Expenses work where "Download Source File" is still a manual step before Slack
- →Expenses work that only reaches Slack when a webhook arrives, when someone remembers to start it

From download to running in 3 steps
- 1Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.
- 2Connect. Add your own credentials on the app nodes - n8n highlights exactly which ones need them.
- 3Activate. Run it once to test, then toggle Active. The automation is live.
What you'll learn
Core levelA compact production shape: validation and error handling without extra machinery.
- •Pulling text out of an uploaded file before parsing it
- •Validating required fields before the write
- •Moving data between Telegram, Notion and Slack in a single run
Every node carries its own documentation on the canvas, plus notes explaining why the architecture was built this way, a credential setup guide, troubleshooting, and three practice exercises. Sample data comes pinned to the trigger, so you can hit Execute and watch data flow before connecting a single account.
Common questions
What exactly do I get?
The complete, ready-to-import n8n workflow as a JSON file, delivered instantly after payment. Import it into your own n8n (cloud or self-hosted), add your credentials, and it runs.
How do I import it into n8n?
In n8n, open Workflows, click the three-dot menu, choose “Import from File”, and select the downloaded JSON. Then connect your own app credentials on the highlighted nodes.
Do I need anything else for it to work?
You need your own n8n instance and accounts/credentials for the apps this workflow connects to (Slack, Notion, HTTP / REST API, Telegram). No coding is required.
What if it doesn't work for me?
If the file is faulty, won't import, or isn't as described, contact us within 7 days and we'll fix it or refund you - see our refund policy.
Can I modify or resell it?
You can freely adapt and use it in your own or your clients' projects. Reselling or redistributing the template file itself is not permitted.
